• coordinate stated in text
• small collection-level geographic resolution
When: Magnesian Conglomerate Formation, Rhaetian (208.5 - 201.3 Ma)
• Late Triassic deposits infill Early Carboniferous (Dinantian) marine limestones
• bed-level stratigraphic resolution
Environment/lithology: fissure fill; limestone and dolomitic, yellow, sandy breccia

• Agrosaurus specimen was originally believed to have been collected from the NE coast of Australia by the H.M.S. Fly in 1844, but this was later shown to be in error, and these materials represent additional Thecodontosaurus specimens from Durdham Down.

? Kuehneosauridae indet.2 Romer 1966 crown diapsid BRSMG Cb4196, rib: "Considering the archosauromorphs identified from the Durdham Down deposit, an alternative identification is as an ulna of Terrestrisuchus (Crush, 1984), which is of similar size and cross section, but the absence of epiphyses means that the decision between kuehneosaur rib or crocodylomorph ulna must be left open."
